Explanation:
Length contraction, according to Einstein's Theory of Relativity, is a phenomenon in which the length of an item is measured to be less than its proper length, which is the length measured in the object's rest frame. Lorentz contraction is a phenomenon that occurs when an inertial frame of reference moves at a significant fraction of the speed of light.
